Upper Limb

The robotic upper limb devices are used to rehabilitate people with stroke, disabling injuries, arthritis, stiffness and during postoperative recovery.┬á Restoring hand and arm motor function is essential to preserve patient’s independence in the performance of the activities of daily living (ADLs). The rehabilitation goal is to promote recovery of lost function, to allow independence and early reintegration into social and domestic life.

Clinical targets for robotic upper limb devices :

  • Weakness of specific muscles,
  • Abnormal muscle tone,
  • Abnormal postural adjustments,
  • Lack of mobility,
  • Abnormal movement synergies,
  • Loss of joint coordination,
  • Loss of sensitivity.

The most effective rehabilitative interventions are those providing early, intensive, task-specific, and multisensory stimulation. Neural damage cannot be replaced by cellular proliferation, partial compensation might be provided by adaptive mechanisms, including variations in neural schemes through the unmasking of hidden neural pathways and synapses which, although not normally used, might emerge when the dominant system fails. Robotic rehabilitation is not merely a matter of increasing the amount and intensity of therapy. In fact, robotic systems may be used not only to produce simple and repetitive stereotyped movement patterns, as well as for most of the existing devices, but also to generate a more complex, controlled multisensory stimulation of the patient. Robot-aided rehabilitation program induces brain reorganization strengthens.
The robots also help to monitor patients’ progress by keeping detailed records of exercise regimes and patient responses.

Modes of robotic rehabilitation:

  • Passive movement in which the robotic device moves the patient’s arm.
  • Active nonassist mode in which the subject executes the exercise and the robot provides no help.
  • Active assist mode in which the subject attempts to move, and the robot provides assistance when there are some voluntary but inadequate movements.
  • Resistive mode when the subject is required to perform an exercise against an antagonist force provided by the robot.
  • Bimanual exercise in which active movement of the unaffected arm is mirrored by simultaneous active/passive/assistive movement of the affected arm by means of the robotic device.
